The clamping-heads 13 and 14:at those edges that terminate short of but close to the alining-board 9when the latter is in working position are provided with hingedsupplemental sections or cleats 17, that are adapted to be turned intopositions in which they diverge from each other, as shown in Fig. L.Each hinged supplemental section 17 is provided with a rigidly-securedoperating-bar 18.

2 The free ends of these operating-bars 18 project in oppositedirections and each follows quite closely one side of the oscillatingsupporting-frame 2 and cooperates with a camnosed spring latch-hook 19,secured at one end to the adjacent side of the said frame 2. When theoperating-bars 18 are forced toward the side of the frame 2 far enoughto bring the supplemental sections 17 into a straight line with theirrespective clamping-heads, the spring latch-hooks 19 engage said barsand lock said supplemental sections in operative positions. The movableclamping-head 14: is moved by a screw-rod 20, which works through theupper transverse portion of the frame 2 and is swiveled at its lower endto a bearing 21 on said head. At its outer end said screwrod is providedwith a hand-wheel 22, by means of which it may be readily turned.

Operation: The operation of the device may be briefly stated as follows:While the alining-board 9 is held in operative position on the frame 2and the said frame is turned substantially in the position indicated inFig. 3, the leaves of the book are placed within the frame between theclamping-heads and against the said alining board. Then the movableclamping-head 14: is tightly pressed against the leaves, so that thesaid leaves are firmly held between the two clamping-heads.

Then the frame 2 is turned upside down or substantially into theposition indicated in Fig. L, and the alining-board is removed from theframe. When the spring-hooks 19 are sprung outward, the supplementalsections of the clamping-head are released and may then be moved intoinoperative positions, as shown in Fig. 4. Then the glue or adhesivematerial is applied to the upper edges of the leaves and is worked inbetween the leaves by running the finger or a tool up and down over thereleased edges of the leaves. Then after the adhesive material has beenworked in between the edges of the leaves the supplemental 'erativepositions, so as to squeeze out from between the edges of the leaves allsurplus adhesive material, and thereby press the stuck edges of theleaves within the same space occupied by the loose portions of theleaves. The said supplemental sections should of course be left lockedin their operative positions long enough to permit the glue or adhesivematerial to set. While the leaves are still clamped by the supplementalsections 17 the cloth backing or binder should of course be applied tothe adhered edges of the leaves.

The utility and convenience of the device above described will beapparent to all persons familiar with bookbinding, and it will also beunderstood that the said device makes it possible to do betterbookbinding by the use of adhesive material without stitching or sewingthan has hitherto been possible or at least practicable. In short, asalready indicated, by the use of the above-described device books may bebound by the use of adhesive material and without stitching or sewingwhich are capable of being opened flat without breaking the back of thebookthat is, without splitting apart the bound edges of the leaves.

From what has been said it will of course be understood that the devicedescribed is ca-.

pable of many modifications within the scope of my invention as hereinset forth and claimed.

It will of course be understood that the bookbinding-press hereindisclosed is capable books, pamphlets and magazines, catalogues, &c., aswell as larger books.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

1. Abookbinding-press comprising a supporting-frame, having cooperatingclampingheads, movable one with respect to the other, to clamp theleaves of books of different thickness, at least one of saidclamping-heads being formed with a supplemental section, movable to andfrom an operative position respectively to clamp and release those edgesof the leaves to which the adhesive material is to be applied, the saidframe being open to permit of such application of the adhesive material,and means for locking or holding the said supplemental clamping-sectionin working position, and whereby when said supplemental section is ininoperative position, the adhesive material may be worked in between theedges of the leaves.

2. A bookbinding-press, comprising a reversible supporting-frame, havinga detachable alining-board, and a pair of clampingheads, at least one ofwhich clamping-heads is formed with a hinged supplemental sectionadjacent to said detachable alining board, which supplemental section ismovable to and from operative position respectively to clamp and releasethose edges of the leaves to which the adhesive material is to beapplied.

3. A bookbinding-press comprising an 0scillating supporting-frame,having a detachable alining-board, and a pair of clampingheads, one ofwhich clamping-heads is movable with respect to the other, and both ofwhich clampingheads are provided with hinged supplemental sections forclamping and releasing those edges of the leaves to which the adhesivematerial is to be applied, substantiallv as described.

4. A bookbinding-press, comprising a supporting-pedestal, an oscillatingframe supported thereby, and provided with a pair of clamping-headshaving hinged supplemental clamping-sections, means for locking saidsupplemental sections in operative positions and for releasing them, ascrew-rod for moving one of said clamping-heads, and a detachablealining-board, applicable to said oscillating frame in a positionadjacent to the supplemental sections of said clamping-heads,substantially as described.

5. In a bookbindingpress, the combination with a supporting-pedestal,and an oscillating supporting-frame supported thereby, of means forlocking said frame in different positions with respect to said pedestal,a pair of clamping-heads carried by said supporting-frame, one thereofbeing fixed and the other movable with respect thereto, saidclampingheads having hinged supplemental clamping-sections, spring-latchdevices for holding said supplemental sections in operative positionsand for releasing them, and a screw-rod for adjusting the movableclamping-head, said screwrod reacting on said oscillatingsupportingframe, and a detachable aliningboard applicable to saidoscillating frame adjacent to the supplemental sections of saidclampingheads, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 31st day of March,

\VESLEY STRINGER. \Vitnesses:
